Explanation / Answer

Question 4 :

Answere :

C). Poly-A tail - Chemical modification of transcript that is added to 3'end.

D). Branch site - a residue of 18-40 bp upstream of the 3' splice site that plays a role in lariat formation.

G). Open reading frame - term used to refer to a protein coding stretch of that begins with a start codon and ends with a stop codons.

O). tRNA - adapters molecule that are responsible for delievering amino acino acids to the site of polypeptides synthesis.

N). Large subunit - portion of ribosome that is the part of intial transcribing complex.

H). Shine Dalgarno Sequence - portion of prokaryotic mRNA that the initiator complex itially bind to.

B). Ef-tu - Prokaryotic transcription factor that restore the ribosome to it's original conformation by hydrolyzing GTP.

M). Release factor - Class of protein responsible for for bringing transcription to halt.

A). Prokayotic cell - Types of cell that produce polycistronic mRNA.

I). Wobble - Term used to describe mechanism by which anticodon pair with codon that they are not prefectely complementary to.
